Technical Support

Hi Everyone,

I have been experiencing an intermittent black screen on my Toradex device where the display unexpectedly goes dark for a few seconds, even though the system remains active.

Iam not sure if this issue is related to firmware, hardware, or configuration settings.

Has anyone encountered a similar problem, and could you recommend any troubleshooting steps or solutions? Thanks in advance for your help!

Hello,

I’m sorry to hear about the intermittent black screen issue you’re experiencing with your Toradex device. Here are some steps you can take to troubleshoot and potentially resolve the problem:

  1. Check Display Connections: Ensure that all cables and connectors between the display and the Toradex module are secure and undamaged. Loose or faulty connections can often lead to display issues.

  2. Review Display Configuration: Verify the display settings in your device’s configuration files. Make sure the resolution and refresh rate are correctly set for your specific display.

  3. Firmware and Software Updates: Confirm that your device is running the latest firmware and software updates. Sometimes, outdated firmware can cause compatibility issues with displays.

  4. Monitor System Logs: Check the system logs for any error messages or warnings related to the display. You can use the dmesg command or check logs in /var/log/ to identify any relevant messages.

  5. Test with a Different Display: If possible, connect a different display to the device to see if the issue persists. This can help determine whether the problem is with the display itself or the Toradex module.

  6. Inspect Power Supply: Ensure that the power supply to the device is stable and sufficient. Inadequate power can sometimes lead to display issues.

  7. Check for Overheating: Overheating can cause temporary hardware malfunctions. Make sure the device is adequately cooled and not overheating.

By following these steps, you can narrow down the potential causes of the black screen issue. If the problem persists after these checks, further investigation into specific hardware or software components related to the display functionality may be necessary.

I hope this helps resolve your issue. If you have any more questions, feel free to ask!

Best regards,

Hi @cowem

Can you give a minimal description of your issue?

  1. What is the module and carrier board you are using?
  2. What is the OS and version you are using?
  3. What type of Display are you using?

You can get you device information information with this command.

Iam using Toradex Apalis iMX8 with Ixora V1.2 carrier board, running TorizonCore 5.7.0. The display is HDMI 1080p panel, and it randomly goes black screen for a few seconds before recovering.

I have checked connections and logs but found nothing unusual. Could this be a firmware or driver issue? Any suggestions would be appreciated!

@cowem

Can you provide those “logs” that you have checked?

Also, can you provide the output of this command?
